PCB Net Routing Assistance
Diagnostic confirmed: the L2/L3 zones have copper geometry but are
missing net assignments (effectiveNetId is null), so DRC treats them
as decorative copper, not net-bound planes.
Fix in two steps:
STEP 1 — Create missing zones with explicit net assignment
The L2 GND zone and L3 3V0 dominant zone do not exist as proper
queryable nodes. Create them now:
a) L2 GND PLANE
- Layer: Mid-Layer 1 (L2)
- Net: GND (assign explicitly — set effectiveNetId / net property)
- Shape: circle, diameter 57.4mm, centred at (0, 0) — slightly smaller than the 58mm board outline to maintain 0.3mm edge clearance
- Fill type: solid copper pour
- Connection style: thermal relief to net-matching pads
- Thermal relief: 4 spokes, 0.4mm spoke width, 0.3mm clearance
- Stitching density: 2mm
b) L3 3V0 DOMINANT POUR
- Layer: Mid-Layer 2 (L3)
- Net: 3V0 (assign explicitly)
- Shape: circle, diameter 57.4mm, centred at (0, 0), MINUS the two existing island regions (VSYS and 1V8_SGP41) — i.e., the 3V0 pour fills L3 everywhere EXCEPT inside the islands
- Fill type: solid copper pour
- Connection: thermal relief, same parameters as L2
STEP 2 — Assign net to existing islands
The L3 VSYS and L3 1V8_SGP41 island zones exist but have no net
assignment. Set them now:
c) L3 VSYS ISLAND
- Existing zone at (10, 18), 10×12mm
- Net: VSYS (assign explicitly — currently has no effectiveNetId)
d) L3 1V8_SGP41 ISLAND
- Existing zone at (-10, 22), 8×8mm
- Net: 1V8_SGP41 (assign explicitly)
After Step 1 and Step 2:
- Force a pour rebuild / fill regeneration on all 4 zones
- Verify each zone now reports a valid effectiveNetId matching its intended net
- Re-run DRC and report:
- New total airwire count
- Specifically the GND, 3V0, VSYS, 1V8_SGP41 airwire counts
- Render each layer (L1, L2, L3, L4) separately so I can verify the copper fills look correct
Expected result: airwire count should drop dramatically (from 170 to
under 30), because most of the GND/3V0/VSYS airwires resolve through
the now-net-bound planes.
If after this the count is still > 50, do NOT iterate further. Report
back and stop. I'll handle the next decision from outside Flux.
Thought for 10 sec
I’ll attempt the four-zone net binding exactly as specified, then verify DRC and layer rendering. First I’m checking whether the layout editor exposes net assignment for copper pours; if it does, I’ll apply the plane fixes and validate immediately.
Thought for 22 sec
Blocked: I can’t complete this safely because the current layout controls do not expose any editable net/effectiveNetId/net-name property for zones. I verified that
connectedLayers, shape, stitching, and thermal-style rules exist, but net, Net Name, and effectiveNetId are not valid editable zone rules.I did not create more decorative copper, because that would repeat the same failure mode. The next decision needs to happen outside this interface: bind the copper pours to nets in the PCB editor/API, then rerun DRC and layer renders.

Placement Review Fixes
Latest targeted fixes before lock-and-route
No placement lock and no auto-routing were run.
Fix 1: Y1 32.768 kHz crystal proximity
Moved:
Table
| Component | Final X (mm) | Final Y (mm) | Notes |
|---|---|---|---|
| Y1 | -11.90 | -18.90 | Moved beside U4 oscillator pins |
| C15 | -14.20 | -20.00 | 12 pF load capacitor near Y1 OSC1 side |
| C16 | -10.00 | -20.00 | 12 pF load capacitor near Y1 OSC2 side |
Relevant U4 pad positions from the 2D layout:
Table
| Pad | X (mm) | Y (mm) |
|---|---|---|
| U4 P0.00 | -11.80 | -17.69 |
| U4 P0.01 | -11.00 | -17.69 |
| Y1 OSC1 | -12.66 | -18.90 |
| Y1 OSC2 | -11.14 | -18.90 |
Checks:
- Y1 centre to U4 P0.00: 1.21 mm.
- Y1 centre to U4 P0.01: 1.51 mm.
- Y1 OSC1 to U4 P0.00: 1.49 mm.
- Y1 OSC2 to U4 P0.01: 1.22 mm.
- C15 centre to Y1 OSC1: 1.90 mm.
- C16 centre to Y1 OSC2: 1.55 mm.
- L2 is configured as a continuous GND plane; this provides ground fill under/around the crystal region.
- There is a named keepout/placeholder geometry near the previous crystal area (
Y1 L1 GND Keepout Placeholder) still represented as a layout zone, but it is not a silkscreen text label.
Fix 2: D1 USB ESD proximity
Moved:
Table
| Component | Final X (mm) | Final Y (mm) | Notes |
|---|---|---|---|
| D1 USBLC6-2SC6 | 4.20 | -14.20 | Moved directly above J1 data pads |
Relevant J1/D1 pad positions from the 2D layout:
Table
| Pad | X (mm) | Y (mm) |
|---|---|---|
| J1 DP1 | 2.75 | -16.43 |
| J1 DP2 | 3.75 | -16.43 |
| J1 DN1 | 3.25 | -16.43 |
| J1 DN2 | 2.25 | -16.43 |
| D1 I/O2 left | 3.10 | -15.15 |
| D1 I/O2 right | 5.30 | -15.15 |
| D1 I/O1 left | 3.10 | -13.25 |
| D1 I/O1 right | 5.30 | -13.25 |
Check:
- Nearest D1 data-side pad to J1 DP/DN cluster is about 1.32 mm, so D1 is within the requested 2 mm of J1 D+/D-.
- D1 pad overlaps with J1 pads were cleared after nudging D1 upward.
Fix 3: Annotation silkscreen and visualization cleanup
Deleted the following non-production visualization items:
ZONE A SENSORS placement markerZONE B MCU STORAGE placement markerBattery VHB Adhesive Marker 35mmRear VHB/Kapton adhesive outline 35mmSPS30 Rear Body Outline 40.6mmSPS30 Air Intake Arrow
Previously deleted:
Zone A LabelZone B LabelZone C Label- overlapping placeholder
REFtext instances
Remaining text nodes after cleanup are production-style labels only: bottom revision/product/date/origin text, HAELO/Clip text, component pin-1 indicators, LED A/K labels, battery labels, USB insertion arrow, and test-point labels.
Note: Several layout zones still have internal names containing terms like
L2, L3, Island, or Dominant. These are not silkscreen text strings; they are layout-zone metadata/geometry used by the design rules and power-plane setup.Fix 4: J2 / L1 identity and designator check
- The 5-pin connector at 12 o'clock is physically J2, the B5B-ZR-SM4-TF JST ZH 5-pin SPS30 cable connector.
- J2 is at X=0.00 mm, Y=22.00 mm.
- J2 pads are pins 1-5 plus mounting pads; it is not L1.
- L1 is the DFE201610E-2R2M=P2 2.2 uH buck inductor.
- L1 is at X=4.30 mm, Y=16.60 mm in Zone C near U1 and C9.
- U1 is at X=-0.27 mm, Y=15.50 mm.
- C9 is at X=3.05 mm, Y=14.00 mm.
Approximate placement distances:
- L1 centre to U1 centre: 4.70 mm.
- L1 centre to C9 centre: 2.89 mm.
This keeps L1 in the power zone and close to the buck switching loop components. Final routed loop area still depends on the actual trace path, so it must be verified after routing.
Fix 5: 3D red/grey left-edge artefact
The red/grey object visible at the board edge is not a duplicate electrical component. The available 3D assets are:
round-lipo-40x5-placeholder.gltf— round LiPo placeholder with flying leads.sps30-placeholder.gltf— SPS30 mechanical placeholder.
The connector-with-wires appearance is consistent with the round LiPo placeholder/flying-lead visualization. It is an asset/model, not a schematic component, and it does not add electrical connectivity beyond the schematic nets.
Current review status
A post-change review still reports one overlapping-copper item referencing older placeholder/reference geometry UIDs. The visible placement changes and the new Y1/C15/C16/D1 locations were applied, and component-related overlaps introduced during the moves were cleared. If the stale placeholder reference persists after a layout refresh, it should be removed before manufacturing export.
